In service class UserAdminService, there is a method updateUser().

public interface UserAdminService {
          public void updateUser() throws UserInvalidException ;
}

UserInvalidException is a checked exception.

This is how it is defined in applicationContext-Service.xml 

        <bean id="userAdminService, " parent="txProxyTemplate">
                
                <property name="target">
                        <bean
                                class="com.abc.impl.UserAdminServiceImpl"
                                autowire="byName" />
                </property>
                
                <property name="transactionAttributes">
                        <props>
                                <prop key="internalLoadTreatment">PROPAGATION_NESTED</prop>
                                <prop key="*">PROPAGATION_REQUIRED</prop>
                        </props>
                </property>
        </bean>

If UserInvalidException  is thrown by method updateUser, will the transaction be rolled back ?

Spring's transaction behavior can be applied to any class not just service or JDBC classes. 
True or False

6

The key to the Spring transaction abstraction is the notion of a transaction strategy. A transaction strategy is defined by the org.springframework.transaction.PlatformTransactionManager  interface. 
The TransactionException that can be thrown by any of the PlatformTransactionManager  interface's  is what kind of exception ?

If for a method updateUser , we do not want the rollback for UserNotFoundException , what changes are to be done in the file configuration below ?

<tx:advice id="txAdvice">
  <tx:attributes>
  <tx:method name="updateUser"/>
  <tx:method name="*"/>
  </tx:attributes>
</tx:advice>

In code example below , which transactional advice will take precedence ?

@Transactional(readOnly = true)
public class DefaultFooService implements FooService {

  public Foo getFoo(String fooName) {
    // do something
  }

    @Transactional(readOnly = false, propagation = Propagation.REQUIRES_NEW)
  public void updateFoo(Foo foo) {
    // do something
  }
}
